#4:. Isabel Dos Santos, $3.3 billion – Angolan, Investments
The oldest daughter of Angola’s president, Jose Eduardo dos Santos, she’s the world’s richest black woman. Her connections to power helped her accumulate stakes in blue-chip Angolan companies, according to Forbes.
In Portugal she also owns nearly 7 percent of oil and gas firm Galp Energia along with Portuguese billionaire Americo Amorim. Her assets include a stake in Banco BIC, and 25-percent of Unitel, the largest mobile phone network in Angola.
Here’s what dos Santos said in a FinancialTimes interview: “I don’t do politics. I do business and I’m not a politician. I’ve had business sense since I was very young. I sold chicken eggs when I was 6.”
